Explanation:

rule 01:(addition rule)

if both number contain same sign (like all are positive or negative),

then you have to add the numbers and sign will remain same .

example:(10)

-4 -15 [here both numbers are negtive(same sign),so we have to add ]

= -19

rule 02:(addition rule)

if both number contain different sign , then subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value.

example :(9)

9 - 26 [here subtract 9 from 26 ]

= -17 [as 26 is the larger integer which contains negative sign (-26),

so the sign will negative]

rule 03:(multiplication rule)

negative plus negative = positive [same sign = positive]

neative plus positive =negative [different sign = negative]

example:(22)

-86 -(-19) [negative plus negative = positive]

=-86 + 19 [follow rule 02]

=-67

example:(6)

7 + (-10) [neative plus positive =negative]

=7 - 10 [follow rule 02]

= -3
